Over the past decade, Bart Craane has been working on his PhD thesis on the subject of temporomandibular disorders (TMDs) and the efficacy of physical therapy (PT) in its management. The thesis was successfully defended in the fall of 2012. The present article aims to provide an overview of the studies included in the PhD project and the results obtained, since they are of importance in the care of TMD patients. The article is a compilation of the results obtained in studies composing the thesis; some of the text and figures are adapted and translated from the thesis, while other parts have been published elsewhere (see References).
